TERMINAL CONNECTER AND SUPPORT FOR LINE WIRES Filed Nov. 11, 1929 INVENTOR ATTORNEYS Patented May 10, 1932 PATENT OFFICE ANDREW HIGH, 013 DETROIT, MICHIGAN TERMINAL CONNECTER AND SUPPORT FOR LINE WIRES Application filed November 11, 1929. Serial No. 406,248.

This invention relates to a device for 0011- ne'cting the terminals of line wires and for forming a rigid support therefor. An object of the present invention is to provide a con- '5 necter for the purpose, which is so constructed that either terminal may be quickly and easily disconnected without danger of injury to the lineman, and wherein the parts are so interlocked that the weight of the line Will not effect a disconnection even though the parts become loosened in use. A further object is to provide an efficient, rigid, electrical connection between line terminals, and we to so secure this connection to a suitable insulator, as to insure perfect insulation and a strong and rigid support for the connecter and line. It is also an object to provide certain other new and useful features in the -construct-ion and arrangement of parts, all as hereinafter more fully set forth.

With the above and other ends in view, the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawings, in

whicha Figure 1 is a side elevation of a device illustrative of an embodiment of the present U invention; 80 Fig. 2 is a plan view of the same; and

Fig. 3 is a longitudinal section substantially upon the line 33 of Figure 2.

The device shown in the accompanying drawings is adapted to connect adjacent ends or terminals of wires, cables or lines for the transmission of electric current, and more particularly to those lines carrying high voltages. The arrangement is particularly adapted for supporting the line upon poles or other means commonly employed for supporting such lines, and includes an insulator arranged to effectively insulate the line from the pole or other support and provide a strong and rigid support for the line upon the poles or other means upon which the insulator is mounted.

It is common practice to mount insulators for carrying line wires wherever it is desirable to run such lines and to secure the line 50 wire to each insulator in any suitable manner, such as by a small auxiliary wire wound around the insulator and secured to the line wire, which line is extended across the insulator to be supported thereby. In event that it becomes necessary to break the line Wire at one of these supports, it is necessary to disconnect the wire from the insulator and then cut the line, and the cutting of the line is a very dangerous operation because of the heavy current passing through the line, which, when the wire is severed, causes a flash, which in some instances, has blinded the lineman and often gives him a severe shock.

The main object of the present invention is to provide a support and connecter for lines carrying high voltages, with this connecter so constructed that it forms an efficient electrical connection between terminals of the line at each side of the support, said connection being such that the lineman may disconnect either terminal without danger of injury to himself, and a very strong and rigid support is provided by the connecter for the line.

As shown in the accompanying drawings, 1 indicates a head or bar formed of copper or other metal which will provide a. good elec trical connection between the ends 2 of the line wire which is to be supported. This head 1 is recessed in its lower side as at 3 to receive the upper end of an insulator 4 which may be of any desired configuration and provided with a socket 5 in its lower end which is internally screw threaded in the usual manner to receive the usual supporting pin .6. The insulator is also formed with the usual skirt 7 surrounding the socket 5 to protect the pin 6 by forming a shed for rain running down on the insulator. The socket 3 in the head 1 is formed somewhat larger in diameter and depth than the upper end portion 8 of the insulator which is adapted to be received therein, so that a lead filling 9 or other, suitable metal may be run into the socket 3 between its wall and the surface of the insulator to firmly and rigidly secure the insulator head within the socket. Thebar or head 1 is therefore rigidly secured in place upon the insulator and extends transversely thereof, and to detachably connect the ends 2 of the line wire to the ends of this bar or head 1, terminal connecters or members 10 are )rovided, each terminal being formed with a bore extending inwardly from its end to receive the end 2 of the line wire which is rigidly secured in this bore by means of a screw clamp or pin 11 which is screwed into a lateral opening in the terminal and has a pointed end to engage the end of the wire.

Each end of the bar or head 1 terminates in a longitudinally extending ear 12 which 15 provided with a screw threaded opening to receive a bolt 13, and each terminal 10 is formed with a hook 14 to lie along side the ear 12 and to engage over the bolt 13, said hook being provided with a slot 15 extending inwardly from one side of the hook to receive the belt 1-3. The head 1 is formed at each end with a shoulder 16 in opposed relation to the end of each terminal hook 14, the end of the hook being formed to engage the shoui'der when the terminal is rotated upon the bolt 1-3. The terminal hooks may be readily disengaged from the bolts 13 by loosening these bolts and then lifting the terminal vertically to disengage the heck of the terminal from the bolt, but should the bolt beconie loosened in use, the terminal will not be disconnected from the head, due to the fact that the end of the hook will engage the shoulder 16 when the terminal is rotated upon bolt by the weight of the line wire, and a good electrical connection will be mainhy this engagement of the end of the hook with the shoulder.

As the head 1 is rigidly secured to the insu lat'or 4, the device may be used in any desired position, that is it may be supported u on a vertical pin has shown, or the insulator may be-secured 'i'n'any-other suitable manher and in an inverted position or in "a horizcnta l position, as when the insulator secured to the side of'a vertical support to extend lateral-1y therefrom, or when secured to an overhead support to extend downwardly "therefrom. When the device 'is in use and 'vided by setting the end of the insulator into the-socket in the head andthen pouring a inetal into the socket, said metal uniting with the'head and closely embracing theend of the insulator, thus very firmly and rigidly 'at'tachingthe insulator to the head.

'Gbviously changes in the arrangement and construction of the parts oi. the device may be j'fii'ade within the scope of the appended claims and without'depa'rting from the spirit of the invention, and I do not therefore wish to limit myself to the particular construction shown.

Having thus fully described my invention, what I claim is 1. A terminal connecter and support for line wires including an insulator, a head rigidly secured to "said insulator and formed with an extension and a shoulder adjacent said extension, a member forming a pivot extending from said extension, and a terminal hook member for the end of a line wire formed to detachably engage and turn upon said pivot member, and formed to engage said shoulder and bind thereagainst to prevent disengagement of said terminal member from said pivot member when said terminal member is turned to an angular position relative to said head.

2.- A terminal conne'cter and support for line wires including an insuiator formed with an end bore to receive a supporting member, a head formed with a socket in one side intermediate its "ends to receive an end portion of said insulator, a metal filler in the space between said socket wall and insulator end to rigidly secure said head to said insulator in transverse relation thereto, said head being formed with cars at its ends formed with screw-threaded openings, said head having shoulders adacent to and at one side of said ears, tennina members adapted to be secured to spaced apart ends of a line wire with each terminal member formed with an end hook, and bolts engaging the screw-threaded openings in said ears and ada )ted to be engaged with said hooks to detaci ab'ly connect said terminal members to said head with said hooks engaging said shoulders to prevent disengagement of said hooks from said bolts.

In testimony whereof I affix my signature.
